Dear all

Following up on stitching PDAO paths at the meeting today:

As you know, a 6TiSCH Track can be a lot more complex than a sequence of nodes (see https://tools.ietf.org/html/draft-ietf-6tisch-architecture-24#section-4.5.3)
It results that deploying a Track requires stitching segments into a DODAG from source to destination.
What makes the most sense for a 6TISCH Track is probably that each track is defined as a DODAG local instance for the source. All the PDAO segments would be stitched together into that DODAG to form a Track.
The current draft allows for this but a section that explains it all would certainly be useful.

Are we all OK that I propose some text about that?

All the best

Pascal
